Foxgloves are biennials. The first year after they germinate, they do not flower. The second year, they flower and produce seeds, then they die. Because of this, it is best to leave the flowers on so that they can reseed themselves and you can continue to enjoy them.
Lupines are technically perennials, but they have a short lifespan of only a few years. You can remove the flowers if you want, but you may want to leave a few intact to reseed the plant when it inevitably dies.
